The polymerase chain reaction (PCR) based random amplified polymorphic DNA (RAPD) assay, morphological, physiological, biochemical and antimicrobial susceptibility test methods have been evaluated for use in the taxonomy of isolated thermotolerant Bacillus from Jordanian hot springs, with specific reference to strains Geobacillus stearothermophilus (ATCC 12980), Bacillus circulans (ATCC 4513) a...

Anopheles (Nyssorhynchus) marajoara is a proven primary vector of malaria parasites in Northeast Brazil, and An. deaneorum is a suspected vector in Western Brazil. Both are members of the morphologically similar Albitarsis Complex, which also includes An. albitarsis and an undescribed species, An. albitarsis "B". These four species were recognized and can be identified using random amplified po...

Phenotypic approaches based on metabolic and biological characteristics of Corynebacterium pseudotuberculosis have been limited due to insufficient discrimination between closely related isolates. In this paper we present performance and convenience of three molecular typing methods: BOX-PCR, random amplification of polymorphic DNA (RAPD) and amplification of DNA fragments surrounding rare rest...

Random amplified polymorphic DNA (RAPD) markers have been used for many types of genetic analyses, including genome mapping, genotype fingerprinting, phylogeny reconstruction, and measuring genetic similarities. They suffer from one potential limitation, however, because the PCR that is used to produce informative amplification products often produces artifactual products as well. Optimization ...

Fish health and the aquatic ecosystem are strongly interwoven interrelated. The receives a range of anthropogenic chemicals which have toxicological or lethal effects on animals. aim this study was to determine level induced mutation genomic stability different sub-lethal doses (25%, 50% 75% LC50) heavy metal [Nickel (Ni), Mercury (Hg), Lead (Pb)and Zinc (Zn)] in Clarias gariepinus (Burchell, 1...
